I have a question about the recipe "Lavender & Verbena Scented Blueberry-Apricot Slab Pie" from hardlikearmour. Can I use another kind of fat instead of coconut fat? If yes, which one can be used? Thanks!

You could use chilled vegetable shortening or even lard if you wanted. The shortening (which is 0% water, 100% fat--same as coconut oil) makes the crust nice and flaky, while the butter (about 15% water) imparts an excellent flavor and produces a tender crust.
